3D printing is finding more and more applications in the industrial field and represents a modern additive manufacturing process based on a digital model. There are a number of advantages of additive manufacturing through 3D printing compared to classic manufacturing processes such as: material economy, design optimization, the possibility of rapid prototyping, shortening the design and manufacturing cycle, eliminating errors and many others. Because 3D printed elements are more and more often found in various applications, an investigation is required by material categories and printing positions of the mechanical properties and how the respective landmarks behave in terms of displacements and internal stresses. The investigation of the mechanical characteristics, displacements and internal stresses can be done through laboratory tests on samples classically subjected to traction, bending, torsion. In order to reduce the number of mechanical tests, in order to investigate displacements and internal stresses, we must use finite element analysis methods. In the present work, the finite element analysis of some tensile specimens, 3D printed from ABS+ material, in the horizontal position A, will be presented.. |
